I do! As someone who spent the bulk of his PC career as a caster, no less.
There is a large gaping hole between having the convenient option to maximize your effectiveness, like Druids or Wizards do, or being required to maximize your effectiveness, as to keep up with classes far beyond your power level. The former is just fun with numbers, while the latter can come with enormous amounts of stress and peer pressure - something that, you may note, should never be part of a game you play to entertain yourself. It's the reason I shake my head and walk through the dreaded "Are you sure?" routine when a new player wants to play a Samurai in a group already including a Sorcerer, a Cleric, a Binder and a Warblade, then hope as he inevitably shrugs me off that he doesn't leave the table 1-4 sessions later in grave disappointment.
CoDzillas and their kin also have the option to forgo part or all of strategic planning. In the end, 'there is always a level of force against which no tactics can succeed' - And casters can whip pure murder out of their pruny finger just outside the bathroom for the most part, while a Fighter needs, not just optionally benefits from, his equipment close at all times, feat chains that don't screw him over, tactical feats, PrCs, to take his surroundings into account, to know grapple and AoO rules from the inside out to keep the game running, good distribution of physical stats and Gods know what else.
Your don't have to go over any of those fancy lists to play your Druid in a high-combat campaign. You do that because you like to, it's not some sort of requirement. Playing a Druid without your self-imposed challenge is a no-brainer. All you really need is Natural Spell and a decent Knowledge(Nature) check to stay relevant, while a Fighter goes through constant struggles to achieve a mere fraction of the same.
So, the conventional wisdom is that Fighter = "simple to play but falls behind fast in effectiveness", whilst your experience is "goes through loads of complex-to-play contortions in order to not fall behind quite so much".
Basically, the only difference is that you're deliberately choosing to struggle and strive like mad in your attempts to keep up, whilst others accept the power gap in exchange for the simplicity in play.
